CLEANING THE CONDENSER WITH A BRUSH
- SWITCH OFF the machine and disconnect it from the power supply mains.
- OPEN the panel covering the motor compartment.
- PROCEED to clean the condenser taking care to use the brush in a direction to the wall. Take care of not bending the fins.
CLEANING THE CONDENSER WITH COMPRESSED AIR
- SWITCH OFF the machine and disconnect it from the power supply mains.
- OPEN the panel covering the motor compartment.
PROCEED to clean the condenser using a jet of air to blow from the inside to the outside. During these operations, it is advisable
to check the state of the component parts.
CLEANING THE WATER-COOLED CONDENSER
For units with water-cooled condensers it is advisable for a plumber to carry out cleaning operations using the proper, commer-
cially available, de-scaling additives.

5.3 PERIODIC CHECKS

- Check that the cold room temperature is close to or at the set level.
- Check that the inlet and outlet of the air moved by the condenser are not obstructed in any way.
- Check the amount of ice in the evaporator and if this latter is blocked, carry out a manual defrost cycle. If the problem persi-
sts, modify the defrost parameters.

5.4 LONG PERIODS OUT OF SERVICE

In the event that the machine is left switched off for long periods of time, it is necessary to take the following precautions before
switching it on again.
Before carrying out any operations, disconnect the machine from the main power supply.
- Check that all electrical and/or water supply connections are in good condition and if necessary, call for technical assistance.
- Check that the spaces around the machine air inlet and outlet grids are not obstructed or reduced in any way.

6. SPECIAL MAINTENANCE

The instructions contained in this section are for qualified maintenance personnel.

6.1 PROGRAMMING THE PARAMETERS

All parameters necessary for the correct operation of the machine
have already been programmed into the control panel. In the
event that it becomes necessary to vary some of these parameters,
follow the instructions given below:
Access to the programming mode is obtained by pressing down
the SET button for more than 5 seconds. When PA1 appears on
the DISPLAY press SET again.
Using the  and  buttons to set the password (see technical
documentation, manual 2) and press SET.
Select the parameter to modify and press SET once more. Using
the  and  buttons to set the desired value and confirm the modi-
fication with SET.
To quit the programming mode press repeatedly FNC or don't
press any buttons for at least 10 seconds.
CAUTION!!To render the modifications to machine parameters effective, it is necessary to disconnect the machine from the
mains power and then reconnect it, using the selector switch or thermomagnetic switch. Parameters with previously set "default"
values are shown in the table.
